The most appropriate method of making egg-albumin sol is :
Show Hint
- Break an egg carefully and transfer the transparent part of the content to 100 mL of 5% w/V saline solution and stir well.
- Break an egg carefully and transfer only the yellow part of the content to 100 mL of 5% w/V saline solution and stir well.
- Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the white part of the content to 100 mL of 5% w/V saline solution and homogenize with a mechanical shaker.
- Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the yellow part of the content to 100 mL of 5% w/V saline solution and homogenize with a mechanical shaker.
The Correct Option is A
Solution and Explanation
Boiling the egg would coagulate (denature) the protein irreversibly, so no sol could be made. This eliminates options (3) and (4).
The yolk is not albumin, which eliminates option (2).
So the raw transparent white is stirred into 5% saline (albumin dissolves in dilute salt solution) to give the sol.
Answer: (1) Break an egg carefully and transfer the transparent part of the content to 100 mL of 5% w/V saline solution and stir well.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
